Almost everything I've read about Fallout 4 included the words "eternal" and "time-suck". And of course it is, all of the games in the Fallout series are really dense. They've got a bunch of lore and side-quests hidden in the world and one of my favorite games in the series Fallout: New Vegas might have had the most to do in the open world.
But even though it's easy to lose all of your time playing any one of these games, someone still managed to beat the Fallout: New Vegas in about twenty minutes. The best part about this is that they recorded the whole thing.
In the description of the YouTube video (which is posted below, so if you have about 20 minutes of free time, you should watch it. It's really interesting) they outline how they've built their character in order for him to get through different situations in the Mojave Wasteland. It's kind of intense, especially since they use some glitches/exploits in order to make the player character move faster than usual.
Speedruns are always really interesting to me because the people that complete them seem to do a lot of research into the game. It's almost like they could probably be game designers themselves since they know how to exploit the systems that are put into place by the actual developers. I wonder if any of these skills the speedrunners use in order to finish their respective games at a fast rate can be translated into the real world.
Anyway, if you have the time you can watch the speedrun below!
